Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines, and in particular relates to an eight-mouth mahjong machine and a card pushing component thereof. Background Art

[0002] Each side of the eight-mouth mahjong machine has two card outlets. Among them, the card outlet close to the player is the dealing sequence (mahjong tiles required for the start of the game), and the card outlet close to the center of the mahjong machine is the drawing sequence (used for drawing cards during the game). In this way, the cards can be played separately in the dealing sequence and the drawing sequence, making it easier for players to sort the cards as quickly as possible at the start of the game.

[0003] Obviously, in the eight-mouth mahjong machine, corresponding card storage channels need to be set for the two card outlets respectively, and a card pushing component needs to be set in each card storage channel to push the card dealing sequence and the card drawing sequence forward; and due to the different settings of the two card storage channels, the structure of the card pushing component is also different.

[0004] For example, a Chinese invention patent with announcement number CN109248436B discloses a roller coaster-style eight-mouth fully automatic mahjong machine, in which two card feeding tracks are arranged, and a traction rope is arranged on the inner circle side wall of the card feeding channel. Both ends of the traction rope are fixed on the card pushing winding wheel, and a card pushing head is arranged on the traction rope. When the card pushing winding wheel rotates, the traction rope runs along the card feeding channel, and the card pushing head moves synchronously.

[0005] It can be seen that the mahjong machine needs to be equipped with an independent traction rope, a card pushing winding wheel and a motor for driving the card pushing winding wheel to rotate for the card feeding track; the power cost is relatively high.

[0006] For another example, Chinese utility model patent with publication number CN210131364U discloses a card pulling and raising linkage mechanism and a mahjong machine, in which a C-shaped card pushing channel and a J-shaped card pulling channel are provided; accordingly, a card pushing rod rotating around its fixed end is provided in the mahjong machine, and a card pushing head provided at the free end of the card pushing rod is used to push the mahjong cards in the card pushing channel; and a card pulling mechanism is provided in the card pulling channel to pull the mahjong cards therein.

[0007] Obviously, the mahjong machine also needs to be provided with independent power mechanisms for driving the mahjong tiles forward for the push channel and the pull channel respectively.

[0008] There is currently no card pushing mechanism that can push cards simultaneously in two card storage channels of an eight-mouth mahjong machine. Utility Model Content

[0009] The invention purpose of the utility model is to provide an eight-mouth mahjong machine and a card pushing component thereof, wherein the card pushing component can push cards simultaneously in two card storage channels on the same side of the eight-mouth mahjong machine, thereby saving the power for pushing cards.

[0010] In order to achieve the above-mentioned invention object, the technical solution of the utility model is as follows:

[0011] A card pushing assembly of an eight-mouth mahjong machine comprises a card pushing rod and a driving unit for driving the card pushing rod to swing around a hinge point at its fixed end; the card pushing rod is provided with a first card pushing head and a second card pushing head, and the first card pushing head and the second card pushing head have different card pushing trajectories.

[0012] When pushing cards, the first card pusher and the second card pusher are placed in two card storage channels on the same side of the mahjong machine. When the card pusher rod swings around its hinge point, the first card pusher and the second card pusher are driven to move in their respective card storage channels, achieving the purpose of pushing cards at the same time. This can save half of the card pushing power in the mahjong machine.

[0013] Since the swinging trajectory of the card pushing rod is fixed, while the card pushing trajectories of the first card pushing head and the second card pushing head may not necessarily differ only in radius, it is preferred that in the above-mentioned card pushing assembly, at least one of the first card pushing head and the second card pushing head is movably mounted on the card pushing rod. In this way, the restriction of the card pushing rod on the first card pushing head and the second card pushing head is weakened, so that the first card pushing head and the second card pushing head can adapt to various card storage channels.

[0014] It can be seen that there are three ways to set the pusher rod, the first pusher head and the second pusher head:

[0015] The first type: the hinge point of the card pushing rod is located at the center of the card pushing track of the second card pushing head, and the second card pushing head is fixed on the card pushing rod;

[0016] The hinge point of the card pushing rod is eccentrically arranged relative to the center of a card pushing track of the first card pushing head, and the first card pushing head is movably mounted on the card pushing rod.

[0017] The second type: the hinge point of the card pushing rod is located at the center of the card pushing track of the first card pushing head, and the first card pushing head is fixed on the card pushing rod;

[0018] The hinge point of the card pushing rod is eccentrically arranged relative to the center of a card pushing track of the second card pushing head, and the second card pushing head is movably mounted on the card pushing rod.

[0019] The third type: the hinge point of the card pushing rod is neither at the center of the card pushing trajectory of the first card pushing head nor at the center of the card pushing trajectory of the second card pushing head, and the first card pushing head and the second card pushing head are both movably connected to the card pushing rod.

[0020] The three setting methods are all applicable to the present invention, and the movable setting methods are various. Those skilled in the art can set the specific connection method between the card pushing head and the card pushing rod according to the specific situation, and the present invention has no special requirements for this.

[0021] The following only uses the first card pushing head movable setting to illustrate a method of movable connection between the card pushing head and the card pushing rod for reference.

[0022] That is, in the above-mentioned card pushing assembly, the card pushing rod is formed with a guide rail extending along the length direction of the card pushing rod, and the first card pushing head is formed with a slide groove that slides with the guide rail. When not acted upon by other forces (from the card storage channel), the first card pushing head simply moves along with the swing of the card pushing rod; and when the first card pushing head is acted upon by other forces (from the card storage channel), the first card pushing head moves along the guide rail along with the swing of the card pushing rod.

[0023] Preferably, the above-mentioned card pushing assembly further includes a guide member for leading the first card pushing head to run along a predetermined card pushing trajectory.

[0024] As a further preference, in the above-mentioned card pushing assembly, the guide member includes a guide plate extending along the card pushing trajectory of the first card pushing head, and the guide plate is vertically arranged on the side of the card pushing trajectory of the first card pushing head; the first card pushing head is recessed with a guide groove, and the top edge of the guide plate is received in the guide groove.

[0025] Preferably, in the above-mentioned card pushing assembly, the driving unit comprises a card pushing motor, and a hinge shaft is provided at the hinge point of the card pushing rod; the hinge shaft or the card pushing rod and the output shaft of the card pushing motor are driven by a gear set, or the hinge shaft or the card pushing rod and the output shaft of the card pushing motor are connected by a coupling;

[0026] The gear set includes a driving gear fixedly connected to the output shaft of the card pushing motor, and a transmission gear fixedly connected to the hinge shaft;

[0027] The card pushing rod is provided with a magnet, and the driving unit also includes a starting point magnetic sensor and an end point magnetic sensor on the magnet running path. The starting point magnetic sensor, the end point magnetic sensor and the card pushing motor are all connected to the control module.

[0028] In the utility model, the articulated shaft or the card pushing rod and the output shaft of the card pushing motor can be directly connected through a coupling, or can be transmitted through a gear set. Obviously, using an acceleration gear set for transmission is beneficial to reducing the requirements on the speed of the card pushing motor.

[0029] The utility model also utilizes a magnetic sensor and a magnet to monitor the position of the card pushing rod, thereby controlling the start and stop of the card pushing motor.

[0030] As a further preference, in the above-mentioned card pushing assembly, the outer circumference of the transmission gear is also meshed with at least one stabilizing gear, all the stabilizing gears are in the same circumferential direction of the transmission gear, and the stabilizing gear and the driving gear are in or not in the same circumferential direction of the transmission gear;

[0031] The meshing circle of the transmission gear and the stabilizing gear and the meshing circle of the transmission gear and the driving gear have the same or different radii in the circumferential direction.

[0032] The purpose of setting the stabilizing gear is to keep the transmission gear balanced and ensure that the transmission gear is evenly stressed in the circumferential direction. Therefore, when the number of stabilizing gears is small, they can also be set in the same circumferential direction as the driving gear; and when the number of stabilizing gears is large (two or more), all stabilizing gears are set in the same circumferential direction, and there is no requirement for whether the stabilizing gear and the driving gear are in the same circumferential direction.

[0033] The utility model also provides an eight-mouth mahjong machine, which comprises the above-mentioned card pushing component.

[0034] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0035] (1) The utility model has a first card pushing head and a second card pushing head on the card pushing rod. When pushing cards, the first card pushing head and the second card pushing head are placed in two card storage channels on the same side of the mahjong machine. When the card pushing rod swings around its hinge point, the first card pushing head and the second card pushing head are driven to run in their respective card storage channels, thereby achieving the purpose of pushing cards at the same time. In this way, half of the card pushing power in the mahjong machine can be saved.

[0036] (2) In the present invention, at least one of the first card pushing head and the second card pushing head is movably mounted on the card pushing rod, so that the restriction of the card pushing rod on the first card pushing head and the second card pushing head is weakened, so that the first card pushing head and the second card pushing head can adapt to card storage channels of various directions.

[0038] Figure 2 This is a structural schematic diagram of the card-pushing assembly of the eight-mouth mahjong machine of the utility model from another perspective;

[0039] Figure 3 The present invention is a state diagram of applying the card pushing component of the present invention to an eight-mouth mahjong machine. DETAILED DESCRIPTION

[0040] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, the card pushing assembly of an eight-mouth mahjong machine in this embodiment includes a card pushing rod 1, and the fixed end of the card pushing rod 1 is sleeved on a hinge shaft 2; Figure 3 As shown, in the mahjong machine, the hinge shaft 2 is fixed on the card storage housing 100; therefore, the card pushing rod 1 can rotate around the hinge shaft 2.

[0043] The rotation of the card pushing rod 1 is driven by a driving unit, which includes a card pushing motor (not shown in the figure) and a driving gear 3 fixedly connected to the output shaft of the card pushing motor, and the driving gear 3 is also rotatably connected to the card storage housing 100; a transmission gear 4 is fixedly connected or integrally formed on the card pushing rod 1 and meshes with the driving gear 3 for transmission.

[0044] The outer diameter of the transmission gear 4 can be smaller than the outer diameter of the driving gear 3, which can achieve the purpose of accelerating the rotation of the card pushing rod 1 and reducing the speed of the card pushing motor; obviously, it can also be equivalent to the outer diameter of the driving gear 3.

[0045] At the same time by Figure 2 Visible, combined Figure 3 As shown, the card storage housing 100 is also rotatably connected to two stabilizing gears 5, which are both meshed with the transmission gear 4 and symmetrically located in the same circumferential direction of the transmission gear 4; the function of the stabilizing gear 5 is to keep the transmission gear 4 balanced and ensure that the transmission gear 4 is subjected to balanced force in the circumferential position, which is beneficial to ensure the stable operation of the transmission gear 4 and helps to extend the service life of the transmission gear 4.

[0046] from Figure 2 It can be seen that the two stabilizing gears 5 and the driving gear 3 are not in the same circumferential direction of the transmission gear 4, and the stabilizing gear 5 is located at a lower position. This is to facilitate the arrangement of a monitoring module 6 that is closer to the card pushing rod 1 above the stabilizing gear 5; and, the circumferential radius of the meshing circle of the transmission gear 4 and the stabilizing gear 5 is relatively small, while the circumferential radius of the meshing circle of the transmission gear 4 and the driving gear 3 is relatively large, which can reduce the overall outer diameter of the driving unit; obviously, it is also possible for the circumferential radii of the two meshing circles to be the same.

[0047] The present embodiment also applies to stabilizing gears 5 with one or more than two in number. When the number is more than two, the setting method is the same as above. When the number is only one, it is preferred to set the stabilizing gear 5 to be on the same circumferential direction of the transmission gear 4 as the driving gear 3.

[0048] like Figure 1 and Figure 3As shown, a magnet 11 is fixed on the card pushing rod 1, and the monitoring module 6 in this embodiment includes a substrate 61 installed on the card storage housing 100, and the substrate 61 is provided with a starting point magnetic sensor 62 and an end point magnetic sensor 63 which are located on the running path of the magnet 11, and the starting point magnetic sensor 62, the end point magnetic sensor 63 and the card pushing motor are all connected to the control module.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the card pushing rod 1 is provided with a first card pushing head 7 and a second card pushing head 8, wherein the first card pushing head 7 is used for pushing the card dealing sequence in the first card storage channel 200, and the second card pushing head 8 is used for pushing the card drawing sequence in the second card storage channel 300. Since the first card storage channel 200 and the second card storage channel 300 have the same card inlet but different card outlet positions, the card pushing trajectories of the first card pushing head 7 and the second card pushing head 8 are not only different in their own positions, but also in the center positions of the card pushing trajectories are different.

[0050] Therefore, one of the first card pushing head 7 and the second card pushing head 8 must be movably arranged on the card pushing rod 1. In this embodiment, the hinge point between the card pushing rod 1 and the card storage housing 100 is set to be at the center of the card pushing track of the second card pushing head 8, and the second card pushing head 8 is fixed to the card pushing rod 1; and the hinge point between the card pushing rod 1 and the card storage housing 100 is eccentrically arranged relative to the center of the card pushing track of the first card pushing head 7, that is, the first card pushing head 7 is movably connected to the card pushing rod 1.

[0051] The movable connection between the first card pushing head 7 and the card pushing rod 1 is as follows: a guide rail 12 extending along the length direction of the card pushing rod 1 is formed on the card pushing rod 1, and a slide groove 71 slidably matched with the guide rail 12 is formed on the first card pushing head 7.

[0052] In addition, a guide member is also required to ensure that the first card pushing head 7 runs along a predetermined card pushing track, i.e., the first card storage channel 200. Figure 1 As shown, the guide member includes a guide plate 9 extending along the card pushing track of the first card pushing head 7, and the guide plate 9 is vertically arranged on the side of the card pushing track of the first card pushing head 7. In this embodiment, on the inner wall of the first card storage channel 200; the first card pushing head 7 is recessed with a guide groove 72, and the top edge of the guide plate 9 is received in the guide groove 72.

[0053] The working principle of the card pushing component of the eight-mouth mahjong machine of this embodiment is:

[0054] Before pushing cards, the first card pushing head 7 and the second card pushing head 8 wait side by side outside the card inlet; when sufficient mahjong tiles are stored in the first card storage channel 200 and the second card storage channel 300, the control module starts the card pushing motor to rotate forward, and the card pushing rod 1 starts to rotate under the meshing transmission of the gear set. Since the second card pushing head 8 is fixed on the card pushing rod 1, during the rotation of the card pushing rod 1, the second card pushing head 8 maintains its relative position with the card pushing rod 1 unchanged, and pushes cards from the card inlet along the second card storage channel 300; the first card pushing head 7 is guided by the guide plate 9 to push cards along the first card storage channel 200, and adjusts its relative position with the card pushing rod 1 at any time during the card pushing process;

[0055] When the first card pushing head 7 and the second card pushing head 8 both reach the corresponding card outlets, the end point magnetic sensor 63 detects the magnet 11 on the card pushing rod 1 and sends a signal to the control module. After receiving the signal, the control module stops the card pushing motor from rotating forward and reverses the card pushing motor, and the first card pushing head 7 and the second card pushing head 8 return to their original paths. When the starting point magnetic sensor 62 detects the magnet 11 on the card pushing rod 1, it sends a signal to the control module. After receiving the signal, the control module stops the card pushing motor and waits for the next card pushing.

[0056] Example 2

[0057] The present embodiment is a card pushing assembly of an eight-mouth mahjong machine, and its structure is basically the same as that of Embodiment 1, except that: the hinge point of the card pushing rod 1 is located at the center of the card pushing trajectory of the first card pushing head 7 but is eccentrically arranged relative to the center of the card pushing trajectory of the second card pushing head 8, the first card pushing head 7 is fixed on the card pushing rod 1, and the second card pushing head 8 is movably installed on the card pushing rod 1.

[0058] The movable connection mode between the second card pushing head 8 and the card pushing rod 1 is the same as the movable connection mode between the first card pushing head 7 and the card pushing rod 1; a guide plate also needs to be set on the side of the card pushing track of the second card pushing head 8 to guide the movement of the second card pushing head 8.

[0059] Example 3

[0060] The present embodiment is a card pushing assembly of an eight-mouth mahjong machine, and its structure is basically the same as that of embodiment 1 or 2, except that: the hinge point of the card pushing rod 1 is neither at the center of the card pushing trajectory of the first card pushing head 7 nor at the center of the card pushing trajectory of the second card pushing head 8, and the first card pushing head 7 and the second card pushing head 8 are both movably connected to the card pushing rod 1.
